Description

Die nachfolgende Erfindung betrifft einen rotierbaren Reinigungskopf und eine Reinigungsvorrichtung für Haare und Fell.The following invention relates to a rotatable cleaning head and a cleaning device for hair and fur.

Fell- und Haarbürsten sind bekannt. Neben manuell zu bedienenden Bürsten werden auch elektrisch betriebene angeboten, etwa rotierende Warmluftbürsten. Um Bürsten zu reinigen und beim Bürsten herausgezogene Haare zu lösen sind u. a. auch zylindrische, nicht rotierende Bürsten bekannt, bei denen alle Borsten gleichzeitig in einen Grundkörper eingezogen werden können, damit die Haare von den Borsten abgezogen werden.Fur and hair brushes are known. In addition to manually operated brushes and electrically operated are offered, such as rotating hot air brushes. To clean brushes and to remove hair pulled out during brushing u. a. also cylindrical, non-rotating brushes known in which all bristles can be retracted simultaneously in a body, so that the hair is removed from the bristles.

Die DE 20 2010 008 499 U1 beschreibt eine Haarbürste mit einziehbaren flexiblen Borsten, die ein ortsfestes Außenrohr mit Borstendurchtrittsöffnungen und einen drehbar in dem Außenrohr gelagerten Borstenträger aufweist. Das Außenrohr ist drehfest mit einem Griff verbunden, während der Borstenträger eine Kulissenführung aufweist, mit der eine von einer Betätigungsvorrichtung am Griff erzeugte Linearbewegung in eine Rotationsbewegung gewandelt werden kann. Beim Betätigen der Betätigungsvorrichtung dreht sich der Borstenträger, wodurch alle Borsten unter Durchbiegung nach innen durch die Durchtrittsöffnungen gezogen werden. Dabei lösen sich die Haare von den einzelnen Borsten.The DE 20 2010 008 499 U1 describes a hairbrush with retractable flexible bristles, which has a stationary outer tube with bristle passage openings and a bristle carrier rotatably mounted in the outer tube. The outer tube is rotatably connected to a handle, while the bristle carrier has a slotted guide with which a linear movement generated by an actuator on the handle can be converted into a rotational movement. Upon actuation of the actuator, the bristle carrier rotates, whereby all bristles are pulled under deflection inwards through the passage openings. In doing so, the hair separates from the individual bristles.

Auch aus DE 200 19 552 U1 ist eine ähnliche Bürste mit einziehbaren Borsten bekannt, bei der der Mechanismus zum Einziehen der Borsten nach dem gleichen Prinzip wie bei der vorstehenden Schrift funktioniert. Zusätzlich sind die Borsten dort jedoch schwenkbar um eine Schwenkachse parallel zur Längsachse des Borstenträgers an dem Borstenträger gelagert, sodass auch starre Borsten eingezogen werden können.Also from DE 200 19 552 U1 a similar brush is known with retractable bristles, in which the mechanism for pulling the bristles works on the same principle as in the above scripture. In addition, however, the bristles are pivotally mounted there about a pivot axis parallel to the longitudinal axis of the bristle carrier on the bristle carrier, so that rigid bristles can be fed.

DE 202004009333 U1 zeigt eine Vorrichtung zum Aufnehmen haarähnlicher Fäden mit einem runden Drehkörper mit Borsten, wobei der Drehkörper von einer Welle angetrieben wird. Die Vorrichtung weist einen Abstreifring auf, dessen Mittelpunkt nicht mit dem Mittelpunkt des Drehkörpers übereinstimmt. DE 202004009333 U1 shows a device for receiving hair-like filaments with a round rotating body with bristles, wherein the rotating body is driven by a shaft. The device has a scraper ring, whose center does not coincide with the center of the rotary body.

Einfachere Bürstvorrichtungen ohne das Einziehprinzip sind ebenfalls bekannt: Auch die US 2009/0223008 A1 offenbart eine Bürstvorrichtung, die aus zwei miteinander korrespondierenden Bürstenrollen besteht, wobei die von der letzten Bürstenrolle aufgenommenen Haare an einer Sammelvorrichtung abgestreift werden. Die US 2007/0169720 A1 hingegen offenbart eine einfache Bürstenrolle mit Abstreifkante. Alternativ zum Abstreifen ist aus GB 2 370 754 eine Vorrichtung bekannt, die das Absaugen einer Bürste in der Vorrichtung beschreibt.Easier brushing without the Einziehprinzip are also known: the US 2009/0223008 A1 discloses a brushing device consisting of two brush rolls corresponding to each other, wherein the hairs picked up by the last brush roll are scraped off at a collecting device.

Ausgehend von diesem Stand der Technik liegt der vorliegenden Erfindung die Aufgabe zu Grunde, einen verbesserten rotierbaren Reinigungskopf zu schaffen, der es ermöglicht, einen Reinigungsvorgang kontinuierlich auszuführen. Diese Aufgabe wird durch einen rotierbaren Reinigungskopf mit den Merkmalen des unabhängigen Anspruchs 1 gelöst.Based on this prior art, the present invention based on the object to provide an improved rotatable cleaning head, which makes it possible to carry out a cleaning process continuously. This object is achieved by a rotatable cleaning head having the features of independent claim 1.

Darüber hinaus ergibt sich die Aufgabe, eine Reinigungsvorrichtung zur händischen kontinuierlichen Reinigung von Haaren und Fell zu schaffen.In addition, the task arises to provide a cleaning device for manual continuous cleaning of hair and fur.

Diese Aufgabe wird durch eine Reinigungsvorrichtung mit den Merkmalen des Anspruchs 10 gelöst.This object is achieved by a cleaning device having the features of claim 10.

Weiterbildungen der Vorrichtungen werden durch die Unteransprüche beschrieben.Further developments of the devices are described by the subclaims.

Der erfindungsgemäße Reinigungskopf für Haare und Fell weist in einer ersten Ausführungsform einen rotierbaren hohlen zylindrischen Grundkörper auf, aus dem sich mehrere Reinigungselemente nach außen erstrecken. Erfindungsgemäß ist in dem Grundkörper ortsfest ein Steuerzylinder exzentrisch und in Bezug zu der Längsachse des Grundkörpers parallel angeordnet. Die Reinigungselemente erstrecken sich von der Mantelfläche des Steuerzylinders weg und sind in Führungsöffnungen, die der Grundkörper hat, in Abhängigkeit des Drehwinkels des Grundkörpers verschiebbar gelagert.The cleaning head according to the invention for hair and fur has in a first embodiment, a rotatable hollow cylindrical base body, from which extend a plurality of cleaning elements to the outside. According to the invention, a control cylinder is eccentrically fixed in the main body and arranged parallel with respect to the longitudinal axis of the base body. The cleaning elements extend from the lateral surface of the Control cylinder away and are slidably mounted in guide holes, which has the body, depending on the angle of rotation of the body.

In einer weiteren Ausführungsform können die Reinigungselemente in Abhängigkeit des Drehwinkels des Grundkörpers in diesen versenkt werden, so dass sie sich nicht mehr oder im Wesentlichen nicht mehr über die Oberfläche des Grundkörpers hinaus erstrecken. Dabei bleiben durch das Zurückziehen Schmutzreste und heraus gebürstete Haare an der Oberfläche des Grundkörpers liegen und fallen quasi ab. Mit "im Wesentlichen" ist daher also gemeint, dass sich die Reinigungselemente nur noch höchstens so weit aus der Oberfläche herausstrecken, so dass eben der Schmutz nicht mehr an ihnen hängen bleibt und saubere Reinigungselemente weiter reinigen können, wenn sich der Steuerzylinder dreht - vorteilhaft ist also zur Reinigung der Reinigungselemente keine manuelle Tätigkeit erforderlich.In a further embodiment, the cleaning elements can be sunk depending on the angle of rotation of the base body so that they no longer or substantially no longer extend beyond the surface of the base body. In this case remain by retracting dirt and brushed hair on the surface of the body are and virtually fall off. By "substantially", therefore, it is meant that the cleaning elements only extend out of the surface at most so that the dirt no longer sticks to them and can further clean clean cleaning elements when the control cylinder is rotating - which is advantageous So no manual action required for cleaning the cleaning elements.

Die Reinigungselemente können insbesondere radial in Bezug zum Grundkörper geführt sein, wobei es auch möglich ist, dass die Reinigungselemente in einem von der radialen Richtung abweichenden Winkel darin geführt sind.The cleaning elements may in particular be guided radially with respect to the main body, wherein it is also possible that the cleaning elements are guided therein in an angle deviating from the radial direction.

Es kann sowohl vorgesehen sein, dass die Reinigungselemente einzeln oder aber auch in Gruppen aus ihrer ausgefahrenen Ruhestellung in den Grundkörper eingezogen werden können.It can be provided both that the cleaning elements individually or else in groups from its extended rest position can be fed into the body.

Anders als bei bekannten rotierbaren Reinigungsköpfen liegt beim erfindungsgemäßen Reinigungskopf eine Zwangskopplung der Verschiebeposition der Reinigungselemente und der Rotationsposition des Grundkörpers vor, die durch die exzentrische Anordnung des Steuerzylinders ermöglicht wird, auf dessen Mantelfläche die Reinigungselemente abgleiten.Unlike in known rotatable cleaning heads, a positive coupling of the displacement position of the cleaning elements and the rotational position of the base body is present in the cleaning head according to the invention, which is made possible by the eccentric arrangement of the control cylinder, slide on the lateral surface of the cleaning elements.

Bisherige Reinigungsvorrichtungen kannten entweder die Versenkbarkeit der Borstengesamtheit oder aber die Rotation. Zur Reinigung des Reinigungskopfs selbst war es bisher notwendig, den Reinigungsvorgang zu unterbrechen um die Borstengesamtheit einzuziehen. Beim erfindungsgemäßen Reinigungskopf hingegen werden die einzelnen Reinigungselemente oder Reinigungselementegruppen periodisch eingezogen und somit wird während des Reinigungsvorgangs eine automatische Abreinigung der Reinigungselemente von Haaren oder anderen Verschmutzungen, die sich bei der Reinigung in den Reinigungselementen verhakt haben, ermöglicht. So kann der erfindungsgemäße Reinigungskopf kontinuierlich und ohne händische Zwischenreinigung benutzt werden. Der erfindungsgemäße Reinigungskopf kann außer zur Reinigung von Haaren und Fell auch zur Reinigung von Langhaarteppichen, oder allgemein "haarigen" Oberflächen eingesetzt werden.Previous cleaning devices knew either the retractability of the bristle aggregate or the rotation. For cleaning the cleaning head itself it was previously necessary to interrupt the cleaning process to collect the bristle population. In the cleaning head according to the invention, however, the individual cleaning elements or cleaning element groups are periodically fed and thus an automatic cleaning of the cleaning elements of hair or other contaminants that have hooked in the cleaning in the cleaning elements allows during the cleaning process. Thus, the cleaning head according to the invention can be used continuously and without manual intermediate cleaning. The cleaning head according to the invention can be used except for the cleaning of hair and fur and for cleaning Langhaardppichen, or generally "hairy" surfaces.

Weiter kann der Steuerzylinder einen elliptischen oder nockenförmigen Querschnitt aufweisen.Further, the control cylinder may have an elliptical or cam-shaped cross-section.

Er kann massiv oder als Hohlkörper mit Innenverstrebung ausgebildet sein.It can be solid or designed as a hollow body with Innenverstrebung.

Die Abmessungen, Form und/oder Positionierung des Steuerzylinders im Innenraum des Grundkörpers kann/können in Abhängigkeit der individuellen Anforderungen an eine bestimmte Reinigungsaufgabe angepasst werden. So kann insbesondere die Höhenposition einzelner Reinigungselemente oder Reinigungselementegruppen durch geeignete Gestaltung des Steuerzylinders variabel als Funktion des Drehwinkels des Grundkörpers gestaltet werden. Die Reinigungselemente gleiten dabei im Wesentlichen umfänglich auf der Mantelfläche des Steuerzylinders ab, wobei ihre Ausfahrposition aus dem Grundkörper durch die Spaltweite zwischen der inneren Mantelfläche des Grundkörpers und der äußeren Mantelfläche des Steuerzylinders bestimmt wird. Ein hohler Grundkörper mit Verstrebungen erlaubt es, einen vergleichsweise leichtgewichtigen Reinigungskopf zu bauen, während die Belastbarkeit des Steuerzylinders mit der Belastbarkeit des massiven Steuerzylinders vergleichbar ist.The dimensions, shape and / or positioning of the control cylinder in the interior of the body can / can be adjusted depending on the individual requirements of a particular cleaning task. Thus, in particular the height position of individual cleaning elements or cleaning element groups can be made variable by suitable design of the control cylinder as a function of the angle of rotation of the base body. The cleaning elements slide substantially circumferentially on the lateral surface of the control cylinder, wherein its extended position is determined from the base body by the gap width between the inner circumferential surface of the base body and the outer circumferential surface of the control cylinder. A hollow body with braces makes it possible to build a relatively lightweight cleaning head, while the capacity of the control cylinder is comparable to the capacity of the massive control cylinder.

Darüber hinaus kann sich der Steuerzylinder an einem oder beiden Enden über das jeweilige längsaxiale Ende des Grundkörpers hinaus erstrecken. Dort kann er einen Aufnahmeabschnitt bilden, der dazu vorgesehen ist, drehfest in einer Lagerungsvorrichtung aufgenommen zu werden. Der Steuerzylinder ist also drehfest im Bezug der Lagerungsvorrichtung, während der Grundkörper zur Erfüllung der Reinigungsfunktion drehbar um diesen gelagert ist.In addition, the control cylinder may extend beyond the respective longitudinal axial end of the base body at one or both ends. There it can form a receiving portion, which is intended to be rotatably received in a storage device. The control cylinder is thus rotationally fixed with respect to the storage device, while the main body is rotatably mounted to fulfill the cleaning function.

Ferner können die Reinigungselemente angular versetzt in Reihen parallel zur Längsachse des Grundkörpers angeordnet sein.Furthermore, the cleaning elements can be arranged offset angularly in rows parallel to the longitudinal axis of the base body.

Die Reinigungselemente sind dabei wie Zinken in Kämmen gruppiert und entsprechend einem Kamm, kann dann eine Reihe Zähne bzw. Reinigungselemente über eine gemeinsame Reinigungselementebasis verbunden sein. In diesem Fall heben und/oder senken sich die Reinigungselemente entsprechend als Kamm, dessen Basis in diesem Falle auf dem Steuerzylinder abgleitet. Besonders vorteilhaft können die Reinigungselementebasen an ihrer der Mantelfläche des Steuerzylinders zugewandten Seite eine gleitfördernde Oberfläche haben. Sie können ferner Gleitnuten aufweisen, die in Umfangsrichtung des Steuerzylinders ausgerichtet sind. Die Gleitnuten tragen vorteilhaft dazu bei, dass der erfindungsgemäße Reinigungskopf auch bei eindringendem Schmutz weiterhin funktioniert.The cleaning elements are grouped like combs in combs and corresponding to a comb, then a number of teeth or cleaning elements can be connected via a common cleaning element base. In this case, the cleaning elements raise and / or lower correspondingly as a comb, the base slides in this case on the control cylinder. Particularly advantageously, the cleaning element bases can have a slide-promoting surface on their side facing the lateral surface of the control cylinder. You may also have sliding grooves, which are aligned in the circumferential direction of the control cylinder. The Gleitnuten contribute advantageously to the fact that the cleaning head according to the invention continues to work even with penetrating dirt.

Gemäß einer weiteren Ausführungsform kann eine Rückholvorrichtung operativ mit den Reinigungselementen verbunden sein, die dazu vorgesehen ist, eine Rückholkraft auf die Reinigungselemente auszuüben. Sie bewirkt, dass die Reinigungselemente bzw. Reinigungselementebasen auf der Oberfläche des Steuerzylinders aufliegen. Die Rückholvorrichtung bewirkt, dass sich die Reinigungselemente ohne externe Krafteinwirkung in den Grundkörper zurückziehen. Der Steuerzylinder alleine kann lediglich die Ausfahrbewegung steuern, jedoch nicht die Einfahrbewegung der Reinigungselemente.According to another embodiment, a return device may be operatively connected to the cleaning elements, which is intended to exert a return force on the cleaning elements. It causes the cleaning elements or cleaning element bases to rest on the surface of the control cylinder. The return device causes the cleaning elements retract into the body without external force. The control cylinder alone can only control the extension movement, but not the retraction movement of the cleaning elements.

Die Rückholvorrichtung kann einen oder mehrere Elastomerringe aufweisen, der oder die über die Reinigungselementebasen gestreift ist/sind. Der oder die Elastomerring(e) sollten dabei zumindest über ein Ende der längsaxialen Endabschnitte der Reinigungselementebasen gestreift sein.The retrieval device may include one or more elastomeric rings that are / are striped over the cleaning element bases. The river Oder the elastomeric ring (s) should be at least striped over one end of the longitudinal axial end portions of the cleaning element bases.

Die Rückholvorrichtung kann auch eine Zwangssteuerungsvorrichtung mit einer umlaufenden Steuergasse umfassen. Diese kann insbesondere in einem oder beiden längsaxialen Endabschnitten des Steuerzylinders vorliegen und parallel zu einer Außenkontur des Steuerzylinders verlaufen. Die längsaxialen Endabschnitte der Reinigungselementebasen sind dabei in der Steuergasse geführt.The return device may also include a positive control device with a circumferential control gate. This can be present in particular in one or both longitudinal axial end portions of the control cylinder and extend parallel to an outer contour of the control cylinder. The longitudinal axial end portions of the cleaning element bases are guided in the control gate.

Bei entsprechender Ausgestaltung der Oberflächen der Steuergasse und/oder der längsaxialen Endabschnitte der Reinigungselementebasen tritt durch das Abgleiten der Endabschnitte in der Steuergasse kaum Verschleiß auf, während der Elastomerring stark wechselbeansprucht ist und daher schneller zum Versagen neigt. Zudem ist das aufzubringende Moment zur Rotation des Grundkörpers deutlich größer wenn der Elastomerring eingesetzt wird, da zwischen der äußeren Mantelfläche des Steuerzylinders und den Reinigungselementen eine Reibkraft erzeugt wird und zum Ausfahren der Reinigungselemente stets die Rückstellkraft des Elastomerrings überwunden werden muss, während bei der Ausführungsform mit Zwangssteuerung ein deutlich geringeres Antriebsmoment ausreicht. Wenn ein Steuerzylinder aus Kunststoff zum Einsatz kommt und gängige großserienerprobte Fertigungsverfahren wie Spritzgießen verwendet werden, ist die beschriebene Steuergasse quasi ohne Mehrkosten realisierbar.With appropriate design of the surfaces of the control gate and / or the longitudinal axial end portions of Reinigungselementebasen occurs by the sliding of the end portions in the control gate hardly wear, while the elastomer ring is heavily loaded and therefore tends to failure faster. In addition, the applied torque for rotation of the body is significantly larger when the elastomer ring is used, as between the outer surface of the control cylinder and the cleaning elements, a frictional force is generated and for extending the cleaning elements always the restoring force of the elastomeric ring must be overcome, while in the embodiment with Forced control a significantly lower drive torque is sufficient. If a control cylinder made of plastic is used and common mass-production methods such as injection molding are used, the tax alley described is virtually feasible without additional cost.

Die Reinigungselemente verjüngen sich bevorzugt in einem aus der Mantelfläche des Grundkörpers herausragenden Endabschnitt, es können Borsten, Zinken oder Zähne sein. Besonders vorteilhaft sind asymmetrische Zähne, die eine in Bewegungsrichtung des Grundkörpers ansteigende Spitzenform haben - diese sind besonders geeignet, wenn der Reinigungskopf mit einer Abstreifvorrichtung kombiniert wird - ferner erlauben Zähne mit asymmetrischer Spitzenform eine besonders effektive Haar- bzw. Fellreinigung, da der "Eintauchwinkel" der Zähne in die Fellstruktur vergleichsweise steil ist; die Zähne verhaken sich quasi im Fell um lose Haare effektiv herauszubürsten.The cleaning elements preferably taper in an end section projecting out of the lateral surface of the main body; they may be bristles, prongs or teeth. Particularly advantageous are asymmetrical teeth, which have a rising in the direction of movement of the body tip shape - these are particularly suitable when the cleaning head is combined with a scraper - also allow teeth with asymmetric tip shape a particularly effective hair or coat cleaning, since the "plunge angle" the teeth in the fur structure is comparatively steep; the Teeth get caught in the fur to brush loose hair effectively.

Schließlich kann der Grundkörper drehfest und konzentrisch mit einem Drehmomentüberträger verbunden sein. Bei dem Drehmomentüberträger kann es sich um ein Antriebszahnrad handeln, wobei vorteilhafterweise die innere Mantelfläche des Antriebszahnrads auf einem Lagerungsabschnitt des Steuerzylinders drehbar gelagert ist. Neben dem Antriebszahnrad können auch andere Drehmomentübertragungsvorrichtungen geeignet sein, etwa eine Keilwellenverzahnung, kraftschlüssige Drehmomentübertragungsvorrichtungen oder andere formschlüssige Drehmomentübertragungsvorrichtungen, wie Passfederverbindungen. Der Drehmomentüberträger ist dazu vorgesehen, operativ mit einer Antriebsvorrichtung gekoppelt zu werden. Das Antriebszahnrad kann einstückig mit dem Grundkörper ausgebildet sein oder aber als eigenständiges Bauteil und etwa stoffschlüssig oder unter Zuhilfenahme von Befestigungsvorrichtungen daran gefügt sein.Finally, the body can be rotatably and concentrically connected to a torque converter. In the torque transducer may be a drive gear, wherein advantageously the inner circumferential surface of the drive gear is rotatably mounted on a bearing portion of the control cylinder. In addition to the drive gear, other torque transmitting devices may be suitable, such as a spline, non-positive torque-transmitting devices, or other positive torque-transmitting devices, such as keyways. The torque transmitter is intended to be operatively coupled to a drive device. The drive gear may be formed integrally with the base body or be joined thereto as an independent component and approximately cohesively or with the aid of fastening devices.

Eine weitere Erfindung, die den erfindungsgemäßen Reinigungskopf umfasst, ist eine Reinigungsvorrichtung für Haare und Fell, die einen Haltearm hat, der mit dem eben beschriebenen angetriebenen Reinigungskopf verbunden ist.Another invention, which includes the cleaning head of the invention, is a hair and fur cleaning device having a support arm connected to the powered cleaning head just described.

Der Antrieb des Reinigungskopfs kann über sämtliche bekannte Antriebsarten erfolgen, grundsätzlich auch manuell.The drive of the cleaning head can be done via all known types of drive, in principle, manually.

In einer weiteren Ausführungsform ist mit dem Haltearm eine ortsfeste Abstreifvorrichtung verbunden, die parallel zu der Längsachse des Reinigungskopfs angeordnet ist. Zwischen einer Abstreifkante der Abstreifvorrichtung und der Oberfläche des Grundkörpers liegt hierbei ein Abstreifspalt vor. Die Weite des Abstreifspalts kann an eine zu erledigende Reinigungsaufgabe bzw. an das zu erwartende Verschmutzungsniveau angepasst werden. Der Abstreifspalt darf nicht zu schmal gewählt werden, da die gesamte Reinigungsvorrichtung ansonsten durch übermäßige Schmutzansammlung blockieren könnte. Es kann sogar vorgesehen sein, dass die Weite des Reinigungsspalts unter Verwendung einer Einstellvorrichtung, etwa eines Bewegungsgewindes, einstellbar ist.In a further embodiment, a stationary stripping device is connected to the holding arm, which is arranged parallel to the longitudinal axis of the cleaning head. Between a scraping edge of the stripping device and the surface of the body in this case is a stripping gap. The width of the stripping gap can be adapted to a cleaning task to be performed or to the expected level of contamination. The wiper gap must not be too narrow as otherwise the entire cleaning device could become blocked by excessive dirt accumulation. It may even be provided that the width of the cleaning gap is made using an adjusting device, such as a movement thread, is adjustable.

Gemäß einer noch weiteren Ausführungsform der Reinigungsvorrichtung können die Reinigungselemente des Reinigungskopfs sich an einer Winkelposition der Abstreifkante, höchstens aber bis um den Betrag des Abstreifspalts aus der Mantelfläche des Grundkörpers in den Abstreifspalt erstrecken. Hierdurch soll erreicht werden, dass die Reinigungselemente die Reinigungsvorrichtung nicht berühren. Das Einziehverhalten der Reinigungselemente bzw. Reinigungselementereihen ist dabei durch geeignete Auslegung des Steuerzylinders bzw. seiner Form, Abmessungen und Positionierung innerhalb des Innenraums des Grundkörpers so auszulegen, dass sich sämtliche Reinigungselemente, bevor sie in Bewegungsrichtung an der Abstreifkante vorbeilaufen, mindestens so weit in den Grundkörper zurückziehen, dass der Abstreifspalt freigegeben wird. Bei der Abstreifvorrichtung kann es sich im einfachsten Fall um einen Blechstreifen handeln, dessen eine Kante die Abstreifkante bildet und der in einem mit dem Außenradius des Grundkörpers korrespondierenden Radius gebogen sein kann. Der Biegeradius des Abstreifblechs kann jedoch auch dem Außenradius des Grundkörpers entsprechen. Es kann auch vorgesehen sein, dass an der Abstreifkante eine zusätzliche Abstreiflippe oder Abstreifbürste gelegen ist, die eine weiter verbesserte Reinigung der Oberfläche des Grundkörpers ermöglichen soll.According to yet another embodiment of the cleaning device, the cleaning elements of the cleaning head can extend at an angular position of the wiper edge, but at most up to the amount of Abstreifspalts from the lateral surface of the body in the stripping gap. This is intended to ensure that the cleaning elements do not touch the cleaning device. The pull-in behavior of the cleaning elements or cleaning element rows is to be interpreted by suitable design of the control cylinder or its shape, dimensions and positioning within the interior of the body so that all cleaning elements before they pass in the direction of movement of the wiper edge, at least as far into the body Pull back that the stripping gap is released. In the simplest case, the stripping device can be a metal strip whose one edge forms the scraping edge and which can be bent in a radius corresponding to the outer radius of the main body. However, the bending radius of the stripper can also correspond to the outer radius of the body. It can also be provided that an additional wiper lip or wiping brush is located on the wiping edge, which should allow a further improved cleaning of the surface of the body.

Darüber hinaus kann eine Auffangvorrichtung, bei der es sich um einen Auffangsack oder Auffangbehälter mit starrer Hülle handeln kann, in Bewegungsrichtung hinter der Abstreifvorrichtung am Reinigungskopf angeordnet sein und die vorteilhaft die Abstreifvorrichtung umfasst.In addition, a collecting device, which may be a collecting bag or container with a rigid shell, be arranged in the direction of movement behind the stripping on the cleaning head and advantageously includes the stripping device.

Die Auffangvorrichtung kann auswechselbar am Reinigungskopf angeordnet sein. Alternativ oder zusätzlich kann an der Abstreifvorrichtung ein Absaugsammler angeordnet sein, der entlang einer Absaugöffnung geöffnet ist und der sich parallel zu der Abstreifkante erstreckt. Der Absaugsammler kann darüber hinaus einen Absaugport aufweisen, an den eine Absaugvorrichtung angeschlossen werden kann.The collecting device can be arranged interchangeable on the cleaning head. Alternatively or additionally, a suction collector, which is open along a suction opening and which extends parallel to the scraping edge, can be arranged on the stripping device. The Absaugsammler may also have a suction port to which a suction device can be connected.

"Angeordnet an" bedeutet hier nicht, dass der Absaugsammler tatsächlich mechanisch mit dem Reinigungskopf verbunden sein muss, sondern lediglich, dass er im engeren räumlichen Bereich des Reinigungskopfs respektive der Abstreifvorrichtung vorliegt; er kann problemlos auch an der Lagerungsvorrichtung oder anderen ortsfesten Bauteilen der Reinigungsvorrichtung angeordnet werden. Erst unter Verwendung der Auffangvorrichtung und/oder Absaugvorrichtung ergibt sich eine optimal hygienische und rückstandsfreie Reinigung, da die Umgebung bei der Reinigung weitestgehend sauber bleibt. Die Absaugvorrichtung kann eine externe Saugpumpe oder auch in die Reinigungsvorrichtung integriert sein, wobei es insbesondere vorgesehen sein kann, die Absaugvorrichtung durch den gleichen Antriebsmotor anzutreiben, der auch den Grundkörper antreibt."Arranged on" here does not mean that the Absaugsammler actually must be mechanically connected to the cleaning head, but only that it is present in the narrower spatial area of the cleaning head and the stripping device; it can be easily arranged on the storage device or other stationary components of the cleaning device. Only with the use of the collecting device and / or suction device results in an optimal hygienic and residue-free cleaning, since the environment remains largely clean during cleaning. The suction device may be an external suction pump or integrated into the cleaning device, wherein it may be provided in particular to drive the suction device by the same drive motor, which also drives the main body.

Noch weiter kann die Antriebsvorrichtung einen Antriebsmotor aufweisen, der etwa ein Elektromotor, Pneumatikmotor oder Hydraulikmotor sein kann. Der Antriebsmotor kann ferner über ein Getriebe operativ mit dem Drehmomentüberträger des Grundkörpers des Reinigungskopfs gekoppelt sein. Alternativ oder zusätzlich kann die Antriebsvorrichtung auch einen Energiespeicher aufweisen, etwa einen Akkumulator, der an der Antriebsvorrichtung angeordnet ist und der operativ mit der Antriebsvorrichtung gekoppelt ist. Ferner kann der Reinigungskopf zwischen einem ersten Lagerbügel und einem zweiten Lagerbügel drehbar gelagert sein, wobei der erste Lagerbügel und der zweite Lagerbügel durch einen Verbindungsabschnitt mechanisch verbunden sein können.Still further, the drive device may comprise a drive motor, which may be an electric motor, pneumatic motor or hydraulic motor. The drive motor may also be operatively coupled via a gear to the torque transmitter of the main body of the cleaning head. Alternatively or additionally, the drive device may also have an energy store, such as an accumulator, which is arranged on the drive device and which is operatively coupled to the drive device. Furthermore, the cleaning head can be rotatably mounted between a first bearing bracket and a second bearing bracket, wherein the first bearing bracket and the second bearing bracket can be mechanically connected by a connecting portion.

Insbesondere kann ein elektrischer Stabmotor verwendet werden, wie er etwa aus Elektrowerkzeugen wie Akkuschraubern bekannt ist, und der einen in den Stab integrierten Akku hat. Der erste Lagerbügel, zweite Lagerbügel und der Verbindungsabschnitt bilden die "kraftleitende Struktur" der Reinigungsvorrichtung, also deren Lagerungsvorrichtung. Der Antriebsmotor kann parallel oder senkrecht zur Drehachse des Reinigungskopfs angeordnet sein, wobei auch andere Getriebebauarten als Stirnradgetriebe zum Einsatz kommen können, etwa platzsparende Planetengetriebe. Der Antriebsmotor kann jedoch auch den Reinigungskopf direkt antreiben.In particular, an electric rod motor can be used, as it is known from power tools such as cordless screwdrivers, and has a battery integrated into the rod. The first bearing bracket, second bearing bracket and the connecting portion form the "force-conducting structure" of the cleaning device, so their storage device. The drive motor can be arranged parallel or perpendicular to the axis of rotation of the cleaning head be, although other types of transmissions than helical gear can be used, such as space-saving planetary gear. However, the drive motor can also drive the cleaning head directly.

Gemäß einer weiteren Ausführungsform kann der Verbindungsabschnitt parallel zur Längsachse des Reinigungskopfs angeordnet sein und bevorzugt einen Hohlzylinder umfassen. Alternativ oder zusätzlich kann die Antriebsvorrichtung zumindest teilweise in einem Aufnahmeabschnitt des Verbindungsabschnitts ortsfest aufgenommen sein.According to a further embodiment, the connecting portion may be arranged parallel to the longitudinal axis of the cleaning head and preferably comprise a hollow cylinder. Alternatively or additionally, the drive device may be at least partially received in a receiving portion of the connecting portion fixed.

Die Außenform eines rohrförmigen Verbindungsabschnitts eignet sich dabei besonders gut zur Aufnahme eines Elektromotors. Der zur Verfügung stehende Bauraum wird hierdurch optimal ausgenutzt, wodurch die Reinigungsvorrichtung sehr kompakt gebaut werden kann. Die operative Kopplung des Antriebsmotors und des Drehmomentüberträgers des Grundkörpers des Reinigungskopfs kann in dieser Ausführungsform über ein ein- oder mehrstufiges Stirnradgetriebe erfolgen, dessen Übersetzungsverhältnis jeweils an die Reinigungsaufgabe und die Kennlinie des Motors angepasst werden kann.The outer shape of a tubular connecting portion is particularly well suited for receiving an electric motor. The available space is thereby optimally utilized, whereby the cleaning device can be built very compact. The operative coupling of the drive motor and the torque transmitter of the main body of the cleaning head can be carried out in this embodiment via a single or multi-stage spur gear, the gear ratio can be adapted in each case to the cleaning task and the characteristic of the engine.

Der erste Lagerbügel und/oder der zweite Lagerbügel kann/können des Weiteren eine Aufnahmevorrichtung aufweisen, in der der Aufnahmeabschnitt des Steuerzylinders drehfest aufgenommen und bevorzugt verschraubt ist. Die Reinigungsvorrichtung kann ferner einen Griff aufweisen, der bevorzugt mit dem Verbindungsabschnitt verbunden ist und/oder sich senkrecht von dem Verbindungsabschnitt erstreckt. Der Griff kann jedoch auch vom Antriebsmotor gebildet werden.The first bearing bracket and / or the second bearing bracket may / may further comprise a receiving device in which the receiving portion of the control cylinder is rotatably received and preferably screwed. The cleaning device may further comprise a handle, which is preferably connected to the connecting portion and / or extending perpendicularly from the connecting portion. However, the handle can also be formed by the drive motor.

Insbesondere, wenn es sich bei dem Antriebsmotor um einen Stabmotor handelt, der sich entlang eines Teils seiner Längsachse frei erstreckt, kann durch den Antriebsmotor selbst ein ergonomischer Griff gebildet werden, ähnlich wie bei einem Stabschrauber. In der Ausführungsform, in der der Verbindungsabschnitt auch den Antriebsmotor aufnimmt kann es für eine angenehme Gewichtsverteilung der Reinigungsvorrichtung vorteilhaft sein, wenn der Griff Ausgleichsgewichte enthält.In particular, when the drive motor is a rod motor that extends freely along a portion of its longitudinal axis, an ergonomic handle may be formed by the drive motor itself, similar to a rod wrench. In the embodiment in which Connecting section also receives the drive motor, it may be advantageous for a pleasant weight distribution of the cleaning device when the handle contains balance weights.

Schließlich kann der erste Lagerbügel lösbar mit dem Verbindungsabschnitt verbunden sein, etwa verschraubt, und kann selbst eine Abdeckung für das Getriebe bilden. Der zweite Lagerbügel kann eine Rückholvorrichtung mit einer Steuergasse aufweisen, die im Wesentlichen parallel zu der Außenkontur des Steuerzylinders verläuft und in der die freien Endabschnitte der Reinigungselementebasen geführt sind.Finally, the first bearing bracket may be releasably connected to the connecting portion, such as bolted, and may itself form a cover for the transmission. The second bearing bracket may have a return device with a control gate, which runs substantially parallel to the outer contour of the control cylinder and in which the free end portions of the cleaning element bases are guided.

In einer vorteilhaften Ausführungsform kann die durch die Steuergasse gebildete Zwangssteuerungsvorrichtung an einem längsaxialen Ende des Reinigungskopfs am Führungszylinder vorliegen und am abgewandten längsaxialen Ende des Reinigungskopfs am Lagerbügel. Hierdurch wird eine problemlose Montage der Reinigungsvorrichtung sichergestellt.In an advantageous embodiment, the positive control device formed by the control gate can be present at a longitudinal axial end of the cleaning head on the guide cylinder and at the opposite longitudinal axial end of the cleaning head on the bearing bracket. As a result, a trouble-free installation of the cleaning device is ensured.

In Fig. 1 ist eine beispielhafte erfindungsgemäße Reinigungsvorrichtung 10 in einer perspektivischen Ansicht dargestellt, wobei die Reinigungsvorrichtung 10 in der Schnittebene C-C (siehe Fig. 7 ) geschnitten ist. Im Grunde bilden Lagerungsvorrichtung 2 und der Griff 6 eine Halterung für den Reinigungskopf 1. In Fig. 1 ist der Verbindungsabschnitt 22 der Lagerungsvorrichtung 2 der Reinigungsvorrichtung 10 gezeigt, der parallel zur Längsachse des Reinigungskopfs 1 verläuft und der eine Rippe 221 hat. Die Lagerungsvorrichtung 2 umfasst ferner einen ersten Lagerbügel 23 (siehe Fig. 4 und Fig. 5 ) und einen zweiten Lagerbügel 21 und bildet quasi das "Gehäuse", das eine kraftleitende Funktion hat und in der der Reinigungskopf 1 mit dem Rotationsfreiheitsgrad um die Längsachse gelagert ist. Der Reinigungskopf 1 zeigt einen hohlen kreiszylindrischen Grundkörper 11, der Führungen 111 für die Zähne 12 aufweist, die radial im Grundkörper 11 angeordnet sind. Die Führungen 111 (siehe Fig. 3 ) der Zähne 1 sind an die innere Mantelfläche des Grundkörpers 11 angegossen. Der Grundkörper 11 hat eine vergleichweise geringe Wandstärke, während die Führungen 111 relativ weit nach radial innen reichen, um Verkanten der Zähne 12 zu verhindern.In Fig. 1 an exemplary inventive cleaning device 10 is shown in a perspective view, wherein the cleaning device 10 in the sectional plane CC (see Fig. 7 ) is cut. Basically, storage device 2 and handle 6 form a holder for the cleaning head 1. In Fig. 1 the connecting portion 22 of the storage device 2 of the cleaning device 10 is shown, which runs parallel to the longitudinal axis of the cleaning head 1 and which has a rib 221. The storage device 2 further comprises a first bearing bracket 23 (see Fig. 4 and Fig. 5 ) and a second bearing bracket 21 and forms quasi the "housing", which has a force-conducting function and in which the cleaning head 1 is mounted with the rotational degree of freedom about the longitudinal axis. The cleaning head 1 shows a hollow cylindrical body 11 having guides 111 for the teeth 12, which are arranged radially in the base body 11. The guides 111 (see Fig. 3 ) of the teeth 1 are cast on the inner circumferential surface of the base body 11. The base body 11 has a comparatively small wall thickness, while the guides 111 extend relatively far radially inward in order to prevent tilting of the teeth 12.

Die Zähne 12 sind in angular versetzten Reihen als Kämme angeordnet. Je eine Zahnreihe ist dabei über eine gemeinsame Zähnebasis 122 parallel zur Längsachse des Grundkörpers 11 verbunden, wobei die Längsachse des Grundkörpers 11 mit der Achse der Gewindebohrung 134 des Steuerzylinders 13 zusammenfällt. Der Reinigungskopf 1 reinigt so Felle oder Teppiche oder ähnliches rotierend. Die Rotationsrichtung zur Reinigung ist mit U bezeichnet. Aufgrund der asymmetrischen Form der Reinigungszähne 12, die sich in Bewegungsrichtung U verjüngen, hat der Reinigungskopf 1 in der gezeigten Ausführungsform eine bevorzugte Bewegungsrichtung. Hat der Reinigungskopf 1 hingegen symmetrische Reinigungselemente 12 kann die Reinigung durchaus in beiden Drehrichtungen erfolgen.The teeth 12 are arranged in angularly offset rows as combs. Depending on a row of teeth is connected via a common tooth base 122 parallel to the longitudinal axis of the base body 11, wherein the longitudinal axis of the base body 11 coincides with the axis of the threaded bore 134 of the control cylinder 13. The cleaning head 1 cleans so skins or carpets or the like rotating. The direction of rotation for cleaning is designated by U. Due to the asymmetrical shape of the cleaning teeth 12, which taper in the direction of movement U, the cleaning head 1 in the embodiment shown has a preferred direction of movement. If, however, the cleaning head 1 has symmetrical cleaning elements 12, the cleaning can certainly take place in both directions of rotation.

Im Innenraum 112 des Grundkörpers 11 ist parallel und exzentrisch zur Längsachse ein elliptischer Steuerzylinder 13 angeordnet, auf dem die Zähne 12 mit ihrer Innenseite abgleiten, genauer gesagt gleiten die Zähne 12 mit ihrer Reinigungselementebasis 122 darauf ab. Bei einer Drehung des Grundkörpers 11 werden die Zähne 12 mitgedreht, der Steuerzylinder 13 bleibt jedoch ortsfest. Die Zähne 12 werden durch die drehwinkelabhängige Veränderung des Abstands zwischen dem Steuerzylinder 13 und der inneren Mantelfläche des Grundkörpers 11 pro Umdrehung des Grundkörpers 11 von einer vollständig versenkten in eine vollständig ausgefahrene Stellung überführt. In der gezeigten Ausführungsform gibt es im unteren Bereich des Grundkörpers einen vergleichsweise großen Drehwinkelbereich, in dem die Zähne 12 auf Höchststellung bleiben; dieser Bereich ist der Reinigungs-Winkelbereich.In the interior 112 of the base body 11, an elliptical control cylinder 13 is arranged parallel and eccentric to the longitudinal axis on which slide the teeth 12 with its inside, more specifically, slide the teeth 12 with their cleaning element base 122 thereon. Upon rotation of the main body 11, the teeth 12 are rotated, but the control cylinder 13 remains stationary. The teeth 12 are converted by the rotation angle-dependent change in the distance between the control cylinder 13 and the inner circumferential surface of the base body 11 per revolution of the base body 11 from a fully sunk to a fully extended position. In the embodiment shown, there is a comparatively large angle of rotation range in the lower region of the main body, in which the teeth 12 remain in their maximum position; this area is the cleaning angle range.

Damit die Reinigungselementebasen 122 besonders gut auf dem Steuerzylinder 13 abgleiten, haben sie in ihrem "Fußbereich" einen abgerundeten Querschnitt, was in jeder Winkelposition einen verschleißarmen Linienkontakt mit dem Steuerzylinder 13 ermöglicht. Die drehwinkelabhängige Höhenstellung der Zähne 12 kann an individuelle Anforderungen durch Anpassung des Querschnitts und der Positionierung des Steuerzylinders 13 erreicht werden. In der dargestellten Ausführungsform ist ein Behälter 5 als Auffangbehälter 5 gezeigt, der zugleich so geformt ist, dass er die Abstreifvorrichtung 51 integral umfasst und eine Abstreifkante aufweist. Zwischen der Abstreifkante der Abstreifvorrichtung 51 und der Oberfläche des Grundkörpers 11 ist ein Abstreifspalt. Der Steuerzylinder 13 ist nun so ausgebildet und positioniert, dass die Zähne 12 in Reihen, bevor sie in Bewegungsrichtung U die Abstreifkante passieren, in den Grundkörper 11 eingezogen werden, wobei durch das Einziehen verhakte Haare und anderer Schmutz von den Reinigungszähnen 12 gestreift wird, während die Abstreifkante die Oberfläche des Grundkörpers 11 reinigt und verhindert, dass abgestreifter Schmutz "mitgezogen" wird, insbesondere, wenn an der Abstreifkante ein Lippe oder Bürstenleisten angeordnet ist/sind, was in der Figur jedoch nicht gezeigt ist.Thus, the cleaning element bases 122 slide particularly well on the control cylinder 13, they have in their "foot" a rounded cross-section, which allows a low-wear line contact with the control cylinder 13 in each angular position. The rotational angle-dependent height position of the teeth 12 can be achieved to individual requirements by adjusting the cross section and the positioning of the control cylinder 13. In the illustrated embodiment, a container 5 is shown as a collecting container 5, which is also shaped so that it comprises the scraper device 51 integrally and has a scraper edge. Between the wiping edge of the stripping device 51 and the surface of the main body 11 is a stripping gap. The control cylinder 13 is now designed and positioned so that the teeth 12 in rows, before they pass in the direction of movement U the wiper edge, are drawn into the main body 11, being caught by the entangled hair and other dirt from the cleaning teeth 12, while the wiping edge cleans the surface of the base body 11 and prevents stripped dirt from being "pulled along", in particular when a lip or brush strips is / are arranged on the wiping edge, which is not shown in the figure.

Von der Abstreifvorrichtung 51 abgestreifter Schmutz wird im Innenraum 52 des Auffangbehälters 5 aufgenommen, so dass bei der Reinigung die Umgebung nicht verunreinigt wird. An dem Auffangbehälter 5 kann auch ein Absaugport angeordnet werden, der mit einem Staubsauger verbunden werden kann.Dirt stripped by the stripping device 51 is absorbed in the interior 52 of the collecting container 5, so that the environment is not contaminated during cleaning. At the collecting container 5, a suction port can be arranged, which can be connected to a vacuum cleaner.

Der erfindungsgemäße Reinigungskopf 1 selbst kann an portablen Handgeräten oder an ortsfesten Reinigungsvorrichtungen eingesetzt werden, etwa zur Teppich- oder Tierreinigung.The cleaning head 1 according to the invention itself can be used on portable handsets or stationary cleaning devices, such as for carpet or animal cleaning.

Mit dem erfindungsgemäßen Reinigungskopf 1 ist es erstmals möglich, selbst stark haarende Tiere im Fellwechsel kontinuierlich zu reinigen, ohne ständig die Bürste putzen zu müssen, da die erfindungsgemäße Reinigungsvorrichtung eine automatische Abreinigung der Zähne 12 bietet, die bei jeder Umdrehung des Reinigungskopfs 1 durchgeführt wird, wodurch die Zähne 12, und, bei Verwendung einer Abstreifkante mit Lippe oder Bürstenleiste, sogar der Grundkörper 11 kontinuierlich während der Benutzung gereinigt werden.With the cleaning head 1 according to the invention, it is possible for the first time to continuously clean even heavily haired animals in the change of fur, without having to constantly clean the brush, since the cleaning device according to the invention provides automatic cleaning of the teeth 12, which is carried out with each revolution of the cleaning head 1, whereby the teeth 12, and, when using a wiping edge with lip or brush strip, even the main body 11 are continuously cleaned during use.

Hier ist ein Endabschnitt des Steuerzylinders 13 zu sehen, der von der Rückholvorrichtung 135 umgeben ist, die die Steuergasse 136 aufweist. In der Steuergasse 136 sind die längsaxialen freien Enden der Zähnebasen 122 geführt, wodurch eine Zwangssteuerung der Höhe der Zähne nach dem Prinzip der "Führungskulisse" ermöglicht wird.In Fig. 2 is a perspective view of the cleaning device 10 can be seen, wherein the cleaning device 10 in the plane DD (see Fig. 7 ) is cut. Here is an end portion of the control cylinder 13 can be seen, which is surrounded by the return device 135 having the control gate 136. In the control gate 136, the longitudinal axial free ends of the teeth bases 122 are guided, whereby a forced control of the height of the teeth on the principle of "guide link" is made possible.

Über die Abmessung, Kontur und Position des Steuerzylinders 13, respektive der parallel dazu verlaufenden Steuergasse 136, wird sowohl das Ausfahren als auch das Versenken der Zähne gesteuert. Dies hat den Vorteil, dass bei Verwendung eines Gummirings zur Rückholung viel weniger Verschleiß auftritt. Die Rückholvorrichtung 135 mit Steuergasse 136 kann vorteilhaft in einem Fertigungsschritt zusammen mit dem Steuerzylinder 13 hergestellt werden, etwa durch Spritzgießen, so dass keine Zusatzkosten entstehen. Der Grundkörper 11 des Reinigungskopfs 1 ist drehbar in dem ersten Lagerbügel 23 gelagert, während der Steuerzylinder 13 drehfest zum ersten Lagerbügel 23 ist. Der Steuerzylinder 13 ist im Übrigen materialsparend ausgeführt; er ist im Wesentlichen hohl und hat Verstrebungen 131, die kraftflussgerecht ausgerichtet sind.About the dimension, contour and position of the control cylinder 13, respectively, the parallel thereto control gate 136, both the extension and the sinking of the teeth is controlled. This has the advantage that when using a rubber ring for retrieval much less wear occurs. The return device 135 with control gate 136 can advantageously in a manufacturing step together with the control cylinder 13th be produced, for example by injection molding, so that no additional costs. The main body 11 of the cleaning head 1 is rotatably mounted in the first bearing bracket 23, while the control cylinder 13 is rotationally fixed to the first bearing bracket 23. The control cylinder 13 is otherwise performed to save material; it is essentially hollow and has braces 131 that are aligned with power flow.

Fig. 4 zeigt einen Längsschnitt eines Teils der Reinigungsvorrichtung 10 entlang der Längsmittelebene des Reinigungskopfs 1. Der Steuerzylinder 13 ist zwischen dem ersten Lagerbügel 23 und dem zweiten Lagerbügel 21 drehfest gelagert, wobei die beiden Lagerbügel 21,23 über den Verbindungsabschnitt 22 verbunden sind und zusammen mit diesem die Lagerungsvorrichtung 2 bilden (siehe auch Fig. 5 ). Der Steuerzylinder 13 erstreckt sich beidenends längsaxial über den Grundkörper 11 hinaus und bildet in diesem Bereich jeweils einen Aufnahmeabschnitt 133, in dem er formschlüssig in den jeweiligen Lagerbügeln 21,23 aufgenommen ist, wobei eine Befestigungsschraube 14 zum Einsatz kommt, um die Axialposition vorzugeben. Die drehbare Lagerung des Grundkörpers 11 erfolgt auf der in der Figur linken Seite auf dem Lagerungsabschnitt 132 des Steuerzylinders 13, während auf der in der Figur rechten Seite des Grundkörpers 11 die drehbare Lagerung in einem umlaufenden Lagerungsabschnitt 211 des zweiten Lagerbügels 21 erfolgt. Das Abtriebszahnrad 16 ist hier als separates Bauteil ausgeführt, das drehfest mit dem Grundkörper 11 verbunden ist und das in Eingriff mit dem Zwischenzahnrad 32 steht. Vorteilhaft sind die beiden Zahnräder 16,32 vor Schmutz geschützt innerhalb des ersten Lagerbügels 23 angeordnet, der quasi das Getriebegehäuse bildet. Fig. 4 shows a longitudinal section of a portion of the cleaning device 10 along the longitudinal center plane of the cleaning head 1. The control cylinder 13 is rotatably mounted between the first bearing bracket 23 and the second bearing bracket 21, wherein the two bearing brackets 21,23 are connected via the connecting portion 22 and together with this Form storage device 2 (see also Fig. 5 ).

Advantageously, the two gears 16,32 are protected from dirt within the first bearing bracket 23, which forms the transmission housing quasi.

Gut ist hier auch die kammartige Anordnung der Zähne 12 an gemeinsamen Zähnebasen 122 zu erkennen. Die freien Endabschnitte 124 sind jeweils in Steuergassen 136,213 geführt, die der Zwangsführung der Zähnebasen 122 dienen. An dem in der Figur linken Ende des Steuerzylinders 13 liegt die Steuergasse 136 in dem Steuerzylinder 13 selbst vor, während am rechten Ende des Steuerzylinders 13 die Steuergasse 213 zwischen der Mantelfläche des Steuerzylinders 13 und der Rückholvorrichtung 212 des zweiten Lagerbügels gebildet wird. Diese Anordnung ist notwendig, um die Zähnebasen 122 überhaupt zwischen die beiden Rückholvorrichtungen 135,212 montieren zu können. Die Rückholvorrichtungen 135,212 sorgen dafür, dass die Zähnebasen 122 auf der Oberfläche des Steuerzylinders 13 anliegen bzw. unter Bewegung des Grundkörpers 11 darauf abgleiten. Um ein besonders sanftes sowie geräusch- und verschleißarmes Abgleiten zu ermöglichen, haben die Zähnebasen 122 Gleitnuten 121, die in Umfangsrichtung des Grundkörpers 11 verlaufen.Good here is the comb-like arrangement of the teeth 12 to recognize common teeth bases 122. The free end portions 124 are each guided in control lanes 136,213, which serve the positive guidance of the teeth bases 122. At the left in the figure left end of the control cylinder 13, the control gate 136 is in the control cylinder 13 itself, while at the right end of the control cylinder 13, the control gate 213 between the outer surface of the control cylinder 13 and the return device 212 of the second bearing bracket is formed. This arrangement is necessary in order to be able to mount the teeth bases 122 at all between the two return devices 135, 212. The return devices 135,212 ensure that the teeth bases 122 rest on the surface of the control cylinder 13 or slide on it with movement of the main body 11 thereon. In order to allow a particularly smooth and low-noise and low-wear sliding, the teeth bases 122 have sliding grooves 121, which extend in the circumferential direction of the main body 11.

In Fig. 5 ist schließlich die komplette Reinigungsvorrichtung 10 dargestellt, die den Antriebsmotor (in dem Verbindungsabschnitt 22 geführt), den Reinigungskopf 1, den Auffangbehälter 5, die Lagerungsvorrichtung 2 und den daran angefügten Griff 6 aufweist.
